Ironwood Plant (Eusideroxylon zwageri): Conservation ofBorneo Endemic Species for Ecological and LocalEconomic Sustainability

Abstract

he ironwood tree (Eusideroxylon zwageri), an endemic species of Borneo, possesses
significant ecological and economic value. However, its population continues to decline due to
illegal logging, habitat degradation, and insufficient conservation efforts. This study aims to investigate the contribution of E. zwageri conservation to ecological stability and the improvement
of local community well-being. Using a qualitative method that includes literature review and
field-based observation in conservation areas of East Kalimantan, the study identifies the species’
critical role in maintaining forest biodiversity and supporting sustainable livelihoods. The results demonstrate that conserving ironwood not only safeguards forest health but also enhances
social well-being by providing long-term economic benefits to indigenous communities. This
aligns with the United Nations Sustainable Development Goals, particularly SDG 3 (Good Health
and Well-being), emphasizing the importance of local ecological resources in promoting quality
of life. Therefore, integrated conservation approaches are crucial for sustainable ecological and
social outcomes.
